Monster Cable is basically the Bose of audio cables. Spend tons of money on marketing to make people think they're the best, spend as little as possible on cables, mark them up to offset what they paid to market the cables.
Monoprice is excellent quality for most uses and the prices are great, but if you want top quality (which with that run you might consider) go with Blue Jeans Cable.
You'll likely get a kick out of this...
